Yep. The City States are basically vending machines. Lol. As for the DLL, I highly doubt they will ever release that. Soren Johnson said he had a heck of a fight with 2K Games in order to get the SDK released as there were supposedly legal issues. Who is going to go to bat for Civ players this time? I'd love to be proven wrong of course but I think Firaxis/2K Games is much more interested in churning out DLC than releasing the DLL.
